Description: 摘 要:姿态信息是飞行控制中最关键的参数之一,因此姿 态测量成为飞行控制系统首要解决的问题。利用多MEMS 传感器研制了一种微型姿态测量系统。利用三轴MEMS加 速度计和三轴MEMS陀螺数据,由方向余弦矩阵的姿态表 示形式推导了扩展Kalman滤波方程,解算出飞行器的俯仰 角和横滚角;设计专家系统判断飞行器的运动状态,并根据 该状态调整滤波算法中的测量噪声矩阵,使系统可同时满足 静态情况和动态情况的使用;利用空速和高度数据对俯仰 角进行修正,利用GPS解算航向角。将实验结果与国外最新 的商用自动驾驶仪的姿态结果进行了比较,二者在静态情况 下非常吻合,在动态情况下基本吻合。
